The viseshown. by Figs. 1 to 8, inclusive, comprises a iframe including abase V15, an outer standard '16, proj eoting .outward4 from uthe base and constituting a IiXed jaw, and =an .inner standard ,1.7, also projecting outwardffrom the hase. T he standardsmand, the base `are ,preferably fiiormedy as a single, cast.- ing, the lstandards beingk spaced apart to l permit the ,interposition therebetween ofthe movablejaw next described.

y 18 .designa-tes a Vmovable, ,jaw preenably pivoted at'19 to the base, ,and adapted `to "cooperate with the fixed jaw in grasping a body 20, which may be of cylindrical, or 1 other form. .-lPreferahly each ,jaw is proyvided with a plurality .of .recessed gripping faces, each conforming'to the body 20,.'said tacesbeing of diii'erentsizes, andrprefenably "formed Iin facingnmembers detachablxy v.se-

i arm of the cured tothejaws, ashereina-fter described.

The vise includes movable jaw-operating mechanism including a lhand lever `21, *ifulcrumed at 22=ontheinner standarid'lf-.pressureLtransmitting'means operable by lafmovement or' thelever 'to theposition -show-n'by y Fig. 2, to press the. swinging jaw toward-the v'ixed y]aw, and adjusting means :for varying the pressing: movement ofthe swinging j-aw,

- and-.thusenabling -the jaws to conform :to

bodies of various sizes. I embody saidvadj'usting means in affulcrum stud-Q3 i4 and'), journaled in bearings '24, on fthe inner standard 1f?, andan eccentric 25 on said stud, journalled in a soc'lret26, iforlned in an element of 'the pressure-transmitting means. -Said element is,`in 'this instance, a toggle-arm 27, adapted to oscillate on 41jthe .eccentric and vconnected by `a Lpivot `pin '28 '(F 8) with onel end ott atoggleilink), 'the opposite `end ofwhich is connectedby a pivot .pin 30, with the swinging ljaw 18. The toggle-arm an'dglinlrare conneoted bythe pivot Vpin 28 with, one end of ja' connecting link 31, vthe opposite end'o whichV is'fconnected by a pi-vot be'll-cranllever, `composed of al longer `and .a shorter arm. y

Vhen the toggle formed lby the arin Yandlink') is straightened or rendered axetive, as shown by Lfull Ylines'inf-Fig. `8,"t`he v:movable j aw is itorced toward thexedvja'w, an d when 'the tqggleis broken, ,as 4shownhy dotted linjes,'the` movable jaw 'is retracted. L It will now be seen that Vapar-tial:rotation of the pivotstudwill :socha'nge lthe radial position of the Leccentric 25, as lto varythe throw or forward lmovementfimp arted'bythe pivot 4stud to 'the swinging jaw. :The pivot stud l is ,provided with alknurled lprojecting head. 23y by which :it `may lbeV manually rotated. y I 4` Accidental rotation of fthe pivot :stud -is prevented by the eng'gagement ci va 1 spring `detentA 34 with one of `a' series of' notches-S,

finithehead 23a. The pivot stud 23 andits eccentric constitute .a `simple and conveniently operated adjusted means adapted to Ibe used in a vise which,gasishownbyFigsQQ, 10,'and 11a'nd hereinafter' described, does not" include the toggle-'arm V27 andflink "29.

:To prevent injurious "iiexure'and possible Vbreakagefof the base E15, "when Vthe movable jaw isunder pressure, I providefcoirpling means connecting 'the standards "'16 and f1?,

y lpin '132A withthe'shorter l hand lever n21,1the latter being a .also

and including a member 38, carried by one of the standards and provided with an abutment 39, and a member 4() carried by the other standard and provided with a complementa] abutment 41, 'which is pressed against the abutment 39 by strain on the frame tending to Hex the base 15. '.lhe member 38 is preferably an arm cast integra] with the inner standard 17, and. the member 40 is preferably a hook pivoted atv 42 to the outer standai d or fixed jaw i6, and adapted to be displaced, as shown byA dotted lines .in Fig. 2, to a non-obstriicting position permitting free access to the space between the standards. i

vThe described coupling and adjusting means may be employed inV a vise of the type shown by the Callan patent, No. 1,112,192, September 29, 1914. the movable jaw being slidable on the base instead of heilig pivoted thereto. I am not limited, therefore, to a swinging jaw. although I consider the same preferable.

In the embodiment shown by Figs. 9, 10. 11, and 12 the toggle members 27 and 29, and the connecting link 31, are omitted, and the standards 16 and 17 are located closer together than in the embodiment above described. The movable jaw-operating mechanism includes a hand lever 43. fulcrumed on the eccentric 25, and a pressure-transmitting cam 44, constituting the shorter arm of said lever, said cam being in sliding contact with the movable jaw 18,V as shown by Fig. 9. The arrangement is such that when the lever 43 is raised, as shown by full lines, the movable jaw is permitted to recede from. the fixed jaw, and when the lever is depressed, as shown by dotted lines, the movable jaw is forced by the cam 44 toward the fixed jaw. The throw of the movable jaw toward the fixed jaw is determined by rotative adjustment of the eccentric 25, and the stand.- ards are coupled together by the members 38 and 40, as in the embodiment just described.

The recessed gripping faces of the jaws which bear on a body 20, held by the vise, maybe formed directly on the standard 16 and on the movable jaw 18. I prefer, however, to provide as a part of each jaw, a detachable facing member 46` so that the fixed jaw includes a standard member 16, .fixed to the base. and supporting a facing member, while the movable jaw includes a carrying member 18, hinged to the base, and supporting a facing member. The members 16 and 18 are provided with irregular side faces 47 having recessed portions meeting to form projecting portions (Fig. 8) and with opposite edge faces from which spring-pressed detents 48 normally project, as shown by Figs. 3 and 5. The detent-s are preferably balls, movable in sockets 49, and pressed outward by springs 50 against the contracted outer ends 51 of the sockets. The facing members have back faces which are con'lplemental to the fares 47, and are interengaged with the latter to prevent vertical displzu-cment. of the facing members from the positions shown by Fig. 8, said hack faces being` formeril to bear on the recessed side faces 47, and provided with flanges 52. ovei"appiilg the edge faces of the members f6 and 18, and containing recesses 53, formed to be engaged by the detents 48.

lVhen the facing members 46 are forced to place on the membersl 1.6 and 13, the detents 48 are first caused to yield and are then forced outward by the springs into the rcesses 53. 'lhe .facing nieinbers may be removed by exerting outward pressure thereon, sufficient to cause the recesses 53 to inwardly displace the detents. The facing members areprovided with recessed gripping faces 55, which may be of different sizes, as shown by Figure 8, and may be formed to grip bodies 20 of cylindrical or other form.

The interengagement of the irregular faces 47 with the complemental irregular back faces of the facing members 46. relieve the detents 48 and recesses 53 of the duty of" preventing vertical displacement of the facing members from the positions shown by Fig. 8, the only duty required of said detents and recesses being to confine the irregular back faces of the facing members in engagement with the irregular faces 47.

Fig. 7 and 7a show a reducer 56, adapted to be inserted in a recess 55, to adapt the facing member to a .smaller body 20. The reducer is trough-shaped, one of its sides forming a recessed gripping face. The reducer has ears 57 and 58 at its opposite ends, overlapping the edges of the facing member. The ear 58 has a detent 59, which may be a spring-pressed ball, adapted to engage a recess, like the recess 53. in one edge of the facing member. The ear 57 has a setscrew 60, adapted to engage a similar recess in the opposite edge of the facing member.

Any desired number of reducers may be employed, for` example, one for each recess 55.

The fulcrum stud 23 and its eccentric 2.) may be confined against accidental rotation by a brake shoe 61 (Figure 13), movable in a guide 65, in either the arm 27, or the lever 43, and pressed by a spring 62 against the periphery of the eccentric. The spring is adjustably supported by an abutment screw 64. engaged with a tapped portion of the guide 65. I consider this form of contining means preferable to the spring detent 34 engaging the grooves 36, as shown by Figs. 1. 2, 9, a d 10.

I claim:

1. A pipe vise comprising a frame including a base and inner and outer spacedllO apart standards projecting outward from the base, the outer standard constituting a fixed jaw; a movable jaw connected with the base and adapted to cooperate with the fixed jaw; and jaw-operating mechanism including a hand lever fulcrumed on the inner standard, and pressure-imparting means operable by a movement of the lever to press the movable jaw toward the fixed jaw; and coupling means connecting said standards to prevent injurious fleXure of the base when the movable jaw is under pressure, saidv coupling means including a member carried by one of the standards and provided with an abutment, and a member carried by the other standard and provided with a complemental abutment which is pressed against the first-mentioned abutment by strain 0n the frame tending to flex the base.

2. A pipe vise as specified by claim 1, one of said coupling members being pivoted to ythe standard by which it is carried, and separably engaged with the other coupling member, so that it is displaceable to a nonobstructing position.

3. A pipe vise comprising a frame having a base and a. fixed jaw including a standard member, fixed to and projecting outward from the base; a movable jaw including a carrying member movably connected with the base, said members being provided with irregular inner side faces and opposite edge faces, and with spring-pressed detents normally projecting from the edge faces, said jaws including also facing members having irregular back faces complemental to the said irregular inner faces, and flanges formed to overlap said edge faces and provided with recesses adapted to be engaged by said detents to separably hold said irregular faces interengaged with each other, so that the facing members are detachable from the standard member and the carrying mem-V standards projecting outward from the base, l

the outer standard constituting a fixed jaw; a movablel aw connected with the base and adapted to cooperate with the fixedjaw; jaw-operating mechanism including a hand lever fulcrumed on the inner standard, pressure-transmitting means operable by a move-y ment of the lever to press the movable Ajaw towardthe fixed jaw, and adjusting means for varying the pressing-movement imparted to the movable jaw by said pressure-transmitting means, said adjusting means including a fulcrum stud journaled in fixed bearings on the inner standard, and an eccentric on said stud journaled in a socket formed in an'element of the pressure-trans mitting means, so that said socketed element is mounted on the eccentric, said stud being manually rotatable to vary the'position of the socketed element and the throw imparted to the movablejaw, a brake shoe movable in a guide in the socleted element mounted on the eccentric, a spring pressing the shoe against the lperiphery of the eccentric, and an adjustable abutment screw supporting the spring.

In testimony whereof I have affixed my signature.
